jets for tk carbs?

gonna upgrade to pod filters and 4-1 went to my local bike shop and got a qoute on jets they wanted $121.00 + tax is this outrageous?? or is this the norm price?? anyone know of a place where i can get em cheaper? i know i have to go 3 sizes up on the main jet and 1 up on the pilot not for sure whats in it now but im pretty sure its all stock thanks - Shawn

I recently rejetted my 81 GPZ550, it also has the TK carbs. I found several references to using the small slotted main jets for Keihin (sp) carbs.
My local shop charged $9.95 ea, which I thought was a bit high, but he had them and I didn't.
From reading this forum, the pilot jets are not available anymore. I didn't even look for any.
Changing your needle clip setting, or shimming may be the only option for midrange jetting.

Dyno Jet makes Stage 1 and Stage 3 Jet Kits. They are the ame as the old K&N's of years past. Adjustable needle, drills for the slide, and to remove the stoopid(not a spelling error) caps on the air adjusters. Wotrh looking into. Usually sell on ebay as a kit for 1 and 3 for around $96.00.

LOOK! There's some now! :woohoo:

'82-'83 Jet Kit

'84-'85 Jet Kit

What Corey said is probably gonna get you the widest range of tune-ability, and very good instructions on how to select the jetting. Luckily, the TK-22 carbs are the easy to tune since they are not CV. There are just fewer variables with them.

The el-cheapo option is to get a set of tiny drill bits and drill them. It's easier than you think, but you need a drill that has a chuck that closes down almost all the way. The cheap Menards tool-shop brand has a drill that works perfectly, and it's only $10 or $15.

The drill bits can be bought at various tool suppliers like Harbor Freight etc.

An in-between option is to get one of the various rebuild kits that come with jets and adjustable needles. (Some do, some don't.) They should be about $15 to $20 each X 4.

Cool loud; Thanks for the tip. I have bits down to about the diameter of a hair. The sets can be purchased in a neat little holder/organizer, from any jewelry or lapidary supply, or online. They will also sell you a nifty Grobet flex shaft grinder/polisher/drill with a Jacob chuck and foot control. They come in REAL handy, as does a visor with a #7 or #10 lens.

Yeah, hobby shops have them too.

Here's the set I have:

Re-read the top, and at $40.00 per jet, they're smoking something that requires an alligator clip, and someone saying as they pass it to another, "here". :blink:

stage 3 meaning im jumping up 3 jets sizes???

Stages are just the level of performance increase, not necessarily jet sizes.

Stage 1 is for stock air box, stock exhaust, and maybe a K&N drop in air filter.
Stage 3 is for pod filters and aftermarket exhaust system.

If you buy a Stage 3, you'll get a Stage 1 kit in there too.

Bump!

Question: I've still got my stock airbox, but 4-1 exhaust and stock jets - do I need to rejet? Should I go all the way like WG keeps suggesting with 2 steps on the mains and pilots? If so - what jets fit the CV TK-26s?

Do Keihins fit?

Lou - you have these on you GPzs, right? Or are they TK-27s..?

Oh..and how does the sizing of the micro drill bits work? a 61 would be .61mm? So if I have size 32 pilots, I need a 34 drill bit to up the size to .34mm? Same for the mains..a 120 main is 1.2mm?

After doing the coil mod, I notice that my bike kinda 'grunts' when I crank the throttle..it has a much louder/rougher sound to it than normal. I want to say it 'bogs' but it still pulls a lot..so it doesn't really lose power - I don't think anyways.

Thanks!
